    laserland power supplies

    Do you think it has a dpss in that case? The beam flickered and went out and never came on since. Yes I ran it off of 12v 5 amp. Power supply or driver which ever it's called. Could a dpas laser only use 2 wires like direct diode

    laserland power supplies

    It is an RGB no fan on head. There is a power supply or driver board that has the ttl inputs and an rs232 type connector very ssimilar to the B&W laser head connector.
